Docker image needs to be rebuilt to update dependencies for SDKv2

[tbarsballe]

The hosted docker image at planetlabs/notebooks was last updated about 3 years ago, and appears to be on v1.4.6 of the Planet Python Client.
With the release of SDKv2 and the updating of notebooks to use the v2 syntax, the image should likewise be rebuilt and updated so that it has SDKv2 installed.

Currently, when I attempt to run [jupyter-notebooks/orders_api_tutorials/ordering_and_delivery.ipynb][./jupyter-notebooks/orders_api_tutorials/ordering_and_delivery.ipynb] using the docker image, the first step fails with the error:

---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)
<ipython-input-6-3cd3200f6f3c> in <module>
      6 import requests
      7 import planet
----> 8 from planet import Session, DataClient, OrdersClient

ImportError: cannot import name 'Session' from 'planet' (/opt/conda/lib/python3.7/site-packages/planet/__init__.py)

As a warning for whomever ends up building the new image - it seems like the conda env in the docker image doesn't like SDKv2 (testing out a local build failed) so this one may be a bit more complicated than just rebuilding the image. Forcing planet==2.0.0 in the planet-notebook-docker/requirements.txt gave me this:
